Summary: This study analyzed the total contents and chemical forms of 13 hazardous trace elements in fly ash from municipal waste incineration to assess their environmental leaching risk and migration capacity. The results showed significant variations in the content of different trace elements, with the lowest amount recorded for Se and the highest amount for Zn. The risk evaluation demonstrated that all trace elements pose at least a low risk, while Cd and Sb have an extremely high risk level, resulting in a seriously polluted risk for the combined fly ash contamination.

Summary: This study investigates the impact of modified water treatment sludge on the composition and performance of Portland cement composites. It was found that when 10% of the cement was replaced by modified sludge, higher compressive strength was achieved. The modified sludge exhibits pozzolanic activity, improves the compactness of the microstructure, and reduces drying shrinkage.

Summary: This study designed a bioactive glass using waste to improve mechanical properties while maintaining bioactivity performance in vitro. The novel bioactive glasses were prepared using the melt-quenching approach and their bioactivity characteristics were evaluated using phosphate buffer saline as an immersion medium. The results showed that sample 0F had a carbonate apatite phase, while sample 3F had a fluorapatite and calcite phase, supported by the FTIR spectra. The pH also increased for both samples, indicating their bioactivity. Additionally, sample 3F exhibited higher hardness and toughness, supported by the weight gained in the biodegradability analysis. This work offers a promising technique to fabricate bioactive glass incorporating waste for potential dental applications.

Summary: In recent years, there has been increased attention on transportation accidents involving hazardous materials. Previous studies mainly focused on single-vehicle accidents. However, when vehicles carrying hazardous materials gather on a road, potential domino accidents can occur and lead to severe incidents. This paper proposes a quantitative risk assessment (QRA) model that uses a dynamic Bayesian network (DBN) to calculate the probability of leakage and explosion of hazardous chemicals. The model also uses event trees to analyze different scenarios and the probability of domino accidents caused by each scenario. The FN-curve and potential loss of life (PLL) are utilized as metrics to evaluate social risk. A case study in the JinShan District, Shanghai, involving multiple vehicles is analyzed, and the results show that the driver's state, road type, weather factors, and vehicle distance have significant impacts on the societal risk associated with hazardous materials transportation accidents.

Summary: The study found that various pollutants were present in the groundwater and soil of the hazardous waste disposal center, with cadmium exceeding the risk screening value for soil contamination. After conducting a health risk assessment, it was found that under different reuse conditions, the non-carcinogenic and carcinogenic risks of soil pollutants to on-site workers and surrounding residents need to be addressed.

Summary: This study focused on describing an environmentally friendly approach to lubricant disposal, with a particular emphasis on the hazards and composition of mineral-based and vegetable-based lubricants. It was found that while vegetable-based lubricants are considered safe, there are still potential risks associated with their use. Additionally, it was discovered that machining without lubricant could be a viable alternative to reduce environmental and human health risks.

Summary: This study fills the gap in studying waste business characteristics and the performance of a waste management system. The temporal and spatial analyses of the waste management system in Canada are systematically assessed over a 16-year period. The study reveals that the waste business size, waste diversion rates, and employee count are important factors in improving waste management system sustainability.

Summary: Industrial disasters can lead to massive public health problems and environmental damage. The Balikpapan City oil spill resulted in the death of five fishermen, public health problems, and damage to wildlife and ecosystems. A study using risk analysis and GIS mapping found that the major hazmat risks in Balikpapan were flammables and corrosives, with the mining, energy, and oil and gas industries being the main contributors. Coastal areas in Balikpapan were identified as high-risk zones. The industries and government of Balikpapan need to be prepared for disasters by training hazmat responders, ensuring response equipment, monitoring the environment, and establishing disaster communication and coordination.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
